Let daughter's age= d mother's age=m papa's age=p note, d=m/2 and p= m+5 d+m+p=100 therefore, m/2+m+(m+5)=100yrs 5m/2=95yrs m=38yrs. d=38/2=19yrs. p=38+5=43yrs. 4 Likes |

Let the Mother's age be x so Gir's age will be x/2 and Father's age will be (x + 5 ) add up everything and equate it to 100 we have, (x/2) + x + (x+5) = 100 multiply through by 2 to remove the fraction we have x + 2x + 2x + 10 = 200 collect like terms 5x + 10 = 200 5x = 190 x = 190/5 x=38 which is for Mother there half of 38 which is 19 is for daughter's age and x +5 =Father's age 38+5 =43 43 is Father's age |

(dog plus cat) minus (dog plus rabbit) is 24 minus 20; This will give: Dog plus cat minus dog minus rabbit (removing bracket) as 4; Positive dog takes out minus dog leaving Positive cat minus rabbit as 4; We know: Cat plus rabbit is ten; so (cat plus rabbit) plus (cat minus rabbit) will be ten plus 4; Thus, removing the bracket will leave us with: Cat plus cat plus rabbit minus rabbit as fourteen; 2cat is fourteen; Cat is fourteen divided by two which will give 7; ....making dog(seventeen) and rabbit(3); .....giving a combined weight of 27; In so many words...
